-# Rclone Code of Conduct
-
-Like the technical community as a whole, the Rclone team and community
-is made up of a mixture of professionals and volunteers from all over
-the world, working on every aspect of the mission - including
-mentorship, teaching, and connecting people.
-
-Diversity is one of our huge strengths, but it can also lead to
-communication issues and unhappiness. To that end, we have a few
-ground rules that we ask people to adhere to. This code applies
-equally to founders, mentors and those seeking help and guidance.
-
-This isn't an exhaustive list of things that you can't do. Rather,
-take it in the spirit in which it's intended - a guide to make it
-easier to enrich all of us and the technical communities in which we
-participate.
-
-This code of conduct applies to all spaces managed by the Rclone
-project or Rclone Services Ltd. This includes the issue tracker, the
-forum, the GitHub site, the wiki, any other online services or
-in-person events. In addition, violations of this code outside these
-spaces may affect a person's ability to participate within them.
-
-- **Be friendly and patient.**
-- **Be welcoming.** We strive to be a community that welcomes and
-  supports people of all backgrounds and identities. This includes,
-  but is not limited to members of any race, ethnicity, culture,
-  national origin, colour, immigration status, social and economic
-  class, educational level, sex, sexual orientation, gender identity
-  and expression, age, size, family status, political belief,
-  religion, and mental and physical ability.
-- **Be considerate.** Your work will be used by other people, and you
-  in turn will depend on the work of others. Any decision you take
-  will affect users and colleagues, and you should take those
-  consequences into account when making decisions. Remember that we're
-  a world-wide community, so you might not be communicating in someone
-  else's primary language.
-- **Be respectful.** Not all of us will agree all the time, but
-  disagreement is no excuse for poor behavior and poor manners. We
-  might all experience some frustration now and then, but we cannot
-  allow that frustration to turn into a personal attack. It's
-  important to remember that a community where people feel
-  uncomfortable or threatened is not a productive one. Members of the
-  Rclone community should be respectful when dealing with other
-  members as well as with people outside the Rclone community.
-- **Be careful in the words that you choose.** We are a community of
-  professionals, and we conduct ourselves professionally. Be kind to
-  others. Do not insult or put down other participants. Harassment and
-  other exclusionary behavior aren't acceptable. This includes, but is
-  not limited to:
-  - Violent threats or language directed against another person.
-  - Discriminatory jokes and language.
-  - Posting sexually explicit or violent material.
-  - Posting (or threatening to post) other people's personally
-    identifying information ("doxing").
-  - Personal insults, especially those using racist or sexist terms.
-  - Unwelcome sexual attention.
-  - Advocating for, or encouraging, any of the above behavior.
-  - Repeated harassment of others. In general, if someone asks you to
-    stop, then stop.
-- **When we disagree, try to understand why.** Disagreements, both
-  social and technical, happen all the time and Rclone is no
-  exception. It is important that we resolve disagreements and
-  differing views constructively. Remember that we're different. The
-  strength of Rclone comes from its varied community, people from a
-  wide range of backgrounds. Different people have different
-  perspectives on issues. Being unable to understand why someone holds
-  a viewpoint doesn't mean that they're wrong. Don't forget that it is
-  human to err and blaming each other doesn't get us anywhere.
-  Instead, focus on helping to resolve issues and learning from
-  mistakes.
-
-If you believe someone is violating the code of conduct, we ask that
-you report it by emailing [info@rclone.com](mailto:info@rclone.com).

 (Note that you can also replace `go build` with `make`, which will include a

-## Writing Documentation
+## Writing Documentation ##
 
 If you are adding a new feature then please update the documentation.
 
-The documentation sources are generally in Markdown format, in conformance
-with the CommonMark specification and compatible with GitHub Flavored
-Markdown (GFM). The markdown format and style is checked as part of the lint
-operation that runs automatically on pull requests, to enforce standards and
-consistency. This is based on the [markdownlint](https://github.com/DavidAnson/markdownlint)
-tool by David Anson, which can also be integrated into editors so you can
-perform the same checks while writing. It generally follows Ciro Santilli's
-[Markdown Style Guide](https://cirosantilli.com/markdown-style-guide), which
-is good source if you want to know more.
-
-HTML pages, served as website <rclone.org>, are generated from the Markdown,
-using [Hugo](https://gohugo.io). Note that when generating the HTML pages,
-there is currently used a different algorithm for generating header anchors
-than what GitHub uses for its Markdown rendering. For example, in the HTML docs
-generated by Hugo any leading `-` characters are ignored, which means when
-linking to a header with text `--config string` we therefore need to use the
-link `#config-string` in our Markdown source, which will not work in GitHub's
-preview where `#--config-string` would be the correct link.
-
-Most of the documentation are written directly in text files with extension
-`.md`, mainly within folder `docs/content`. Note that several of such files
-are autogenerated (e.g. the command documentation, and `docs/content/flags.md`),
-or contain autogenerated portions (e.g. the backend documentation under
-`docs/content/commands`). These are marked with an `autogenerated` comment.
-The sources of the autogenerated text are usually Markdown formatted text
-embedded as string values in the Go source code, so you need to locate these
-and edit the `.go` file instead. The `MANUAL.*`, `rclone.1` and other text
-files in the root of the repository are also autogenerated. The autogeneration
-of files, and the website, will be done during the release process. See the
-`make doc` and `make website` targets in the Makefile if you are interested in
-how. You don't need to run these when adding a feature.
-
 If you add a new general flag (not for a backend), then document it in
 `docs/content/docs.md` - the flags there are supposed to be in
 alphabetical order.
 
 If you add a new backend option/flag, then it should be documented in
-the source file in the `Help:` field:

-- You can run `make backenddocs` to verify the resulting Markdown.
-  - This will update the autogenerated sections of the backend docs Markdown
-    files under `docs/content`.
-  - It requires you to have [Python](https://www.python.org) installed.
-  - The `backenddocs` make target runs the Python script `bin/make_backend_docs.py`,
-    and you can also run this directly, optionally with the name of a backend
-    as argument to only update the docs for a specific backend.
-  - **Do not** commit the updated Markdown files. This operation is run as part of
-    the release process. Since any manual changes in the autogenerated sections
-    of the Markdown files will then be lost, we have a pull request check that
-    reports error for any changes within the autogenerated sections. Should you
-    have done manual changes outside of the autogenerated sections they must be
-    committed, of course.
-- You can run `make serve` to verify the resulting website.
-  - This will build the website and serve it locally, so you can open it in
-    your web browser and verify that the end result looks OK. Check specifically
-    any added links, also in light of the note above regarding different algorithms
-    for generated header anchors.
-  - It requires you to have the [Hugo](https://gohugo.io) tool available.
-  - The `serve` make target depends on the `website` target, which runs the
-    `hugo` command from the `docs` directory to build the website, and then
-    it serves the website locally with an embedded web server using a command
-    `hugo server --logLevel info -w --disableFastRender --ignoreCache`, so you
-    can run similar Hugo commands directly as well.

-### Guidelines for a speedy merge
+Unit tests
 
-- **Do** use [lib/rest](https://pkg.go.dev/github.com/rclone/rclone/lib/rest)
+  * Create a config entry called `TestRemote` for the unit tests to use
-  if you are implementing a REST like backend and parsing XML/JSON in the backend.
+  * Create a `backend/remote/remote_test.go` - copy and adjust your example remote
-- **Do** use rclone's Client or Transport from [fs/fshttp](https://pkg.go.dev/github.com/rclone/rclone/fs/fshttp)
+  * Make sure all tests pass with `go test -v`
-  if your backend is HTTP based - this adds features like `--dump bodies`,
-  `--tpslimit`, `--user-agent` without you having to code anything!
-- **Do** follow your example backend exactly - use the same code order, function
-  names, layout, structure. **Don't** move stuff around and **Don't** delete the
-  comments.
-- **Do not** split your backend up into `fs.go` and `object.go` (there are a few
-  backends like that - don't follow them!)
-- **Do** put your API type definitions in a separate file - by preference `api/types.go`
-- **Remember** we have >50 backends to maintain so keeping them as similar as
-  possible to each other is a high priority!

-## Keeping a backend or command out of tree
+[Minimal example](https://gist.github.com/terorie/21b517ee347828e899e1913efc1d684f)
-
-Rclone was designed to be modular so it is very easy to keep a backend
-or a command out of the main rclone source tree.
-
-So for example if you had a backend which accessed your proprietary
-systems or a command which was specialised for your needs you could
-add them out of tree.
-
-This may be easier than using a plugin and is supported on all
-platforms not just macOS and Linux.
-
-This is explained further in <https://github.com/rclone/rclone_out_of_tree_example>
-which has an example of an out of tree backend `ram` (which is a
-renamed version of the `memory` backend).

 ## Making a point release
 
 If rclone needs a point release due to some horrendous bug:
 
 Set vars
 
-- BASE_TAG=v1.XX          # e.g. v1.52
+  * BASE_TAG=v1.XX          # e.g. v1.52
-- NEW_TAG=${BASE_TAG}.Y   # e.g. v1.52.1

-- echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
+  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
 
 First make the release branch.  If this is a second point release then
 this will be done already.
 
-- git co -b ${BASE_TAG}-stable ${BASE_TAG}.0

-## Sponsor logos
-
-If updating the website note that the sponsor logos have been moved out of the
-main repository.
-
-You will need to checkout `/docs/static/img/logos` from <https://github.com/rclone/third-party-logos>
-which is a private repo containing artwork from sponsors.
-
-## Update the website between releases
-
-Create an update website branch based off the last release
-
-```console
-git co -b update-website
-```
-
-If the branch already exists, double check there are no commits that need saving.
-
-Now reset the branch to the last release
-
-```console
-git reset --hard v1.64.0
-```
-
-Create the changes, check them in, test with `make serve` then
-
-```console
-make upload_test_website
-```
-
-Check out <https://test.rclone.org> and when happy
-
-```console
-make upload_website
-```
-
-Cherry pick any changes back to master and the stable branch if it is active.
 
 ## Making a manual build of docker
 
-To do a basic build of rclone's docker image to debug builds locally:
+The rclone docker image should autobuild on via GitHub actions.  If it doesn't
+or needs to be updated then rebuild like this.
 
-```console
+See: https://github.com/ilteoood/docker_buildx/issues/19
-docker buildx build --load -t rclone/rclone:testing --progress=plain .
+See: https://github.com/ilteoood/docker_buildx/blob/master/scripts/install_buildx.sh
-docker run --rm rclone/rclone:testing version
+
+```
+git co v1.54.1
+docker pull golang
+export DOCKER_CLI_EXPERIMENTAL=enabled
+docker buildx create --name actions_builder --use
+docker run --rm --privileged docker/binfmt:820fdd95a9972a5308930a2bdfb8573dd4447ad3
+docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
+SUPPORTED_PLATFORMS=$(docker buildx inspect --bootstrap | grep 'Platforms:*.*' | cut -d : -f2,3)
+echo "Supported platforms: $SUPPORTED_PLATFORMS"
+docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
+docker buildx stop actions_builder
 ```
 
-To test the multipatform build
+### Old build for linux/amd64 only
 
-```console
-docker buildx build -t rclone/rclone:testing --progress=plain --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 .
 ```
-
+docker pull golang
-To make a full build then set the tags correctly and add `--push`
+docker build --rm --ulimit memlock=67108864  -t rclone/rclone:1.52.0 -t rclone/rclone:1.52 -t rclone/rclone:1 -t rclone/rclone:latest .
-
+docker push rclone/rclone:1.52.0
-Note that you can't only build one architecture - you need to build them all.
+docker push rclone/rclone:1.52
-
+docker push rclone/rclone:1
-```console
+docker push rclone/rclone:latest
-docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
